Mashable askes the question "What other shifts in Mobile Internet do you expect by 2015"? as part of this article.
The answer for me is easy;
Mobile handsets that finally use off-handset for cpu processing (eg your handset is only a "viewer" to a cloud based processor handling all the real heavy lifting). Lose connection with the cloud you have 'some' functionality but most of it requires 24 x 7 connectivity. It's the only way to get compact, fast and battery life.
